Straight key vs paddles: which should you start with?
Start with a straight key if you want to feel Morse timing in your own hand and you are happy sending at an easy pace. Start with paddles if you want clean timing sooner, less work for your arm, and room to go fast later. Both are good first keys, and plenty of operators end up using both.
The real difference is who does the timing. On a straight key you make every dit, every dah and every gap yourself. On paddles, an electronic keyer makes the dits and dahs, and your hand decides which comes next and when to stop.
How a straight key works
A straight key is a switch on a lever. Press the knob down and two contacts close; let go and a spring lifts the lever and opens them. The tone lasts exactly as long as you hold the knob down, so a dit is a short press and a dah is a press three times as long. The silences are yours too: one unit inside a letter, three between letters, seven between words.
Nothing sits between your hand and the signal. There is no power to supply and nothing to configure beyond the spring tension and the contact gap. It is the classic telegraph key, and its up-and-down motion is the one most people picture when they think of Morse.
The price of that directness is effort. Every element is a separate stroke of the wrist, so H, ...., is four strokes, and the figure 5, ....., is five. At slow and moderate speeds that is a pleasant, steady motion. As speed rises, the strokes have to get shorter and quicker, and a tense arm tires fast. Straight key operators tend to find a speed that suits them and stay there, which is part of the charm. The technique that keeps it comfortable is in How to use a straight key without tiring your arm.
How paddles and a keyer work
Paddles move sideways. By convention, for a right-handed operator, the thumb presses the left paddle for dits and the index finger presses the right paddle for dahs. The paddles do not make the signal directly. They tell a keyer what to send, and the keyer sends it at the speed you set, with exact timing.
Hold the dit paddle and the keyer sends evenly spaced dits until you let go. Hold the dah paddle and it sends dahs. So H is one press of the thumb, released during the fourth dit, rather than four separate strokes, and every dit in it is exactly as long as every other.
With dual-lever paddles and an iambic keyer you can also squeeze both paddles at once, and the keyer alternates dit and dah for as long as you hold them. That turns C, -.-., into one squeeze that starts on the dah side, and the period, .-.-.-, into one squeeze that starts on the dit side. Iambic keyers come in two modes, A and B, which differ in what happens when you let go in the middle of a squeeze; Iambic keying explained: mode A vs mode B walks through both. A single-lever paddle cannot be squeezed, and some operators prefer it for exactly that reason. Single-lever vs dual-lever paddles compares the two.
The keyer itself can be a separate box, a feature built into a radio, or software. What a basic keyer does not do is space your letters and words. Those gaps are still timed by you.
What each one teaches
A straight key teaches the whole rhythm. Because you make every element and every gap, you learn in your hand what one, three and seven units feel like. Faults are easy to hear: dahs that shrink toward dits, letters that run together, word gaps that vanish. A common view among operators is that time on a straight key makes you a better paddle operator later, since you will already know by feel the timing the keyer then does for you. It is an opinion, not a rule.
Paddles teach coordination and economy. With the element timing handled, your attention goes to sequencing: which paddle, when to squeeze, when to release. The new skill is letting go at the right moment, especially in runs of dits like H, S and 5, where releasing a hair late adds an extra dit and turns H into 5. Once that becomes automatic, paddles are fast and restful.
Both teach the spacing between characters. Neither a straight key nor a basic keyer leaves the right gap between letters for you, so one of the most common faults in hand-sent Morse, letters that run together, can happen on either. AN, .- -., sent with too short a gap becomes P, .--., whatever you send it with. Your fist in Morse code has more on hearing and fixing that.
Side by side
| Straight key | Paddles and keyer | |
|---|---|---|
| Motion | Up and down, from the wrist | Side to side, thumb and finger |
| Who times the dits and dahs | You | The keyer |
| Who times the gaps between letters and words | You | You, on a basic keyer |
| Effort as speed rises | Grows quickly | Stays low |
| Needs a keyer | No | Yes: a box, one built into a radio, or software |
| Where it shines | Slow and moderate speeds | Moderate speeds and up |
Comfort is personal. Some people find the broad wrist movement of a straight key relaxing; others feel it in the forearm after twenty minutes. Paddles ask only for small movements of the thumb and finger, though a tense squeeze tires a hand too. If the up-and-down motion bothers your arm, try paddles before you give up on sending.
So which should you start with?
A few honest rules of thumb:
- Choose a straight key if the history draws you, if you mean to send at an easy pace and enjoy it, or if you want to understand Morse timing from the inside before a keyer takes half of it over.
- Choose paddles if you already know you want to go past moderate speeds, if repeated up-and-down strokes bother your arm, or if you would rather build one set of habits than learn one and replace it later.
- Do not let the choice hold you up. Copying by ear is the larger part of learning Morse, and it does not depend on the key at all. Learn the code and practice sending on whatever you have today; you can change keys later.
Between the two sit the bug, a semi-automatic key that makes the dits for you and leaves the dahs to your hand, and the sideswiper, a single lever that moves side to side but times nothing. Both are rewarding once you have a feel for rhythm, and neither is the usual first key.
Trying both on a Mac
You can find out which suits you before you buy any hardware. Dot & Dash has both on a Mac keyboard. As a straight key, Space or the knob of its on-screen machine works like the real thing: a short press is a dit, a longer one a dah, and the app reads your keying at your own speed. Switch to paddles and two keys become the dit and dah paddles, Left Option and Right Option by default, timed at the speed you set, in iambic mode A or B. Many USB Morse keys and keyers type a keyboard key, and you can choose that key in Settings. Paddles need a license once the free 24 hours are over.
Questions
Is a straight key harder to learn than paddles?
At slow speeds it is often easier, because there is only one lever and one motion. It gets harder as you speed up, because you time every element yourself and the strokes have to get quicker.
Can I learn on paddles without ever using a straight key?
Yes. Plenty of operators have only ever sent with paddles. You still have to learn good spacing between letters and words, because a basic keyer does not time those gaps for you.
Which paddle sends the dits?
By convention, for a right-handed operator, the left paddle, pressed with the thumb, sends dits and the right paddle sends dahs. Many keyers let you swap the two, which some left-handed operators prefer.
Do I need a radio to practice with either key?
No. You can practice with a key and a practice oscillator, or on a computer. You need a license only to transmit on the amateur bands, not to learn or practice.
